Madison. Even the non name geeks notice that we have too many Madisons. It was ranked 10 in 1998, but I know more Madisons than Emilys and Caitlins (with all various spellings combined) within two years of my age. But don't underestimate the popularity of Caitlin. Or should I say: Kaitlyn, Kaitlin, Katelyn, Caitlyn and Catelynne?
